Nachtjadt war diaries.

Hello everyone, newbie here. Please call me Ian. The user name is ironic cos i'm anything but. Anyway, my reason for posting is due to the above publications. I was given these books as a gift some time ago. I looked at them but never fully understood their importance from a research/historical viewpoint. The books themselves do not have the shiny outers that I have seen on advertised editions, instead the ones I were given are in a display box/cardboard affair. Whether this is original or not I am unaware. The two books are in mint condition as they have not been used and the box looks as tho its been sat around for a while but still good. Here is the crunch! Are they worth anything? I've seen the eBay listings at £150 and £300+ and the post on this forum from a chap who sold his for 500 euro. I am going to sell mine as my interest is not as in-depth as all that and they take up shelf space, but I want to get as much feedback as possible as to their real value. Feel free to inbox me back.

Ian.
